...Joseph N. Frederick III PSC 1121C Spring 2011 Geophysics Geophysics can be broken down into several groups that deal with physical science and the earth. It is a field and profession that combines geology, mathematics, and physics all in an effort for people across the world to understand the ways of the world and exactly what it takes for certain seemingly unnatural events to happen. Geophysics covers a range of ideas from gravity, heat flow, seismic waves that cause vibrations through the Earth’s layers, radioactivity both geothermal and geochronological, electricity, electromagnetic waves and magnetism, fluid dynamics, and even condensed matter physics. So as we see, geophysics is indeed a very broad subject, yet when looked at under specific lights, we see that geophysics is no more than a name, a container, for all matters Earthly related. Most of these topics will most definitely be covered in this essay and if not talked about in depth, definitely mentioned seeing as how all of these ideas are valuable to everyone worldwide in getting to know and understand the way our home planet works in relation to ourselves and the space we occupy in the universe. (Beroza, Nelson, and Ilich, "The Department of Geophysics"). History The first traces of anything geophysically related first appear in regions inside of China during the Qin dynasty somewhere between two hundred twenty-one and two hundred six B.C. when Chinese fortunetellers used lodestones to create their fortune...

Compared to the theoretical value, our percent error is: Percent Error: 578.4 kJ - 601.8 kJ x 100 % 601.8 kJ = 3.88 % The error can be accounted from mistakes during the experimental process. The Magnesium and the Magnesium Oxide could have been weighed incorrectly. The measuring of the Hydrochloric acid could also have been wrong. Then, there is error from the equipment that we use. Maybe the scale we use for weighing the raw materials was broken. Also, our thermometer could have been...

...with how they react to the elements and retain heat, how fast they heat, and how fast they cool. Heat is based on the total internal energy of the molecules of a body ( Tillery 2009). Larger object tend to have more internal energy than smaller objects, especially if the objects in question are the same substance, but if both object have the same temperature they are believed to have about the same molecular kinetic energy (Tillery 2009). The molecular energy is broken up into two different categories, external and internal energy. The difference between the two is that external energy refers the kinetic and potential energy of an every-day sized object, and internal refers the kinetic and potential energy of the molecules of an object. Take the tire on a car for example, it has external kinetic energy as it is rotating and that energy is transferred to the internal kinetic energy of the molecules between the tire and the surface of the road, which the consequence is both surface of the road and tire to be heated. The amount the road and tire are heated are directly related to how fast the tire is spinning and how much friction is being created between the two surfaces. This also serves as a good example for basic definition of heat, which can be described as the movement that occurs between two objects of different temperature when the objects are brought together. An example would be mixing hot water with cold water. The heat would be transferred to the cold water and the...

...People who live in hot-weather locations know how important it is to have a running, operable AC unit, especially for the hot summer months. Since temperatures often climb to over 100 degrees, the thought of a broken air conditioning system can strike fear in the hearts of those living in the extreme heat. Thankfully, there are some reliable signs to look for when evaluating whether a unit can make it through the hottest days of summer. Take a look at the following to stay prepared: 1. The system is constantly running. In most HVAC systems, the unit is triggered when the temperature in the home reaches a certain point. When the house is too warm, the unit will turn on and work to cool the rooms. Once a desired temperature is achieved, the...

Méliès tackled a wide range of subjects as well as the fantasy films usually associated with him, including advertising films and serious dramas. He was also one of the first filmmakers to present nudity on screen with “Apres le Bal”. (EarlyCinema.com) D. W. Griffith D.W. Griffith, in full David Wark Griffith (born January 22, 1875, Floydsfork, Kentucky, U.S.—died July 23, 1948, Hollywood, California), pioneer American motion-picture director, credited with developing many of the basic techniques of filmmaking, in such films as The Birth of a Nation (1915), Intolerance (1916), Broken Blossoms (1919), Way Down East (1920), Orphans of the Storm (1921), and The Struggle (1931). (Global.britannica.com) The thing that really separated Griffith from other short filmmakers during his time at Biograph was his ability to recognize short film was not the same as a feature, therefore they should not be made in the same way. A short film has a slightly different narrative structure than a feature. Everything has to be set up rather quickly, but Griffith always made sure not to rush the narrative of the stories he was trying to portray. Instead, Griffith would telescope the action to fit within one reel so that he would shorten the story with a title card or narrative device. It was even reported that Griffith would often insist...

...been written by Dowland himself. Lachrimae exists in over 100 manuscripts and printings in different arrangements for ensemble and solo. The Lachrimaes tend to be much more abstract than other music based on dance forms of the time, and do not completely follow the structure of the standard pavan in terms of length of phrases; they are also more contrapuntal. Instrumental versions by Dowland include Lachrimae for lute, Galliard to Lachrimae for lute and Lachrimae antiquae (1604) for consort. Dowland also published Lachrimae, or Seaven Teares (London, 1604), a collection of consort music which included a cycle of seven Lachrimae pavans based on the falling tear motif. Thomas Morley set the "Lachrimae Pauin" for the six instruments of a "broken consort" in his First Booke of Consort Lessons (London, 1599). Other composers have written pieces based on the work, including Jan Pieterszoon Sweelinck and Thomas Tomkins, while John Danyel's Eyes, look no more pays clear homage to the piece, as does John Bennet's Weep, O Mine Eyes. In the 20th century, American composer and conductor Victoria Bond wrote "Old New Borrowed Blues (Variations on Flow my Tears)". Benjamin Britten quotes the incipit of Flow My Tears in his Lachrymae for Viola, a set of variations on Dowland's ayre If My Complaints Could Passions Move. In 2006, the British electronic music group Banco de Gaia produced a vocoded version called "Flow my Dreams, the Android Wept". Lachrimae became one of the favorite improvisational...

...The Rental Heart – Kirsten Logan Without a heart your body is useless. When your heart stops beating, you live until your brain dies from lack of oxygen, but in this short story the narrator lives perfectly fine while changing hearts. This short story is basically about restarting peoples’ ability to love, but also of how real love can overcome technology in place to fake it. This subject is exactly what the main character is dealing with in the short story “The Rental Heart”. That leads me to the setting of the story. The shorty, “The Rental Heart” is written by Kirsten Logan in 2010. We do not know where and when the short story takes place. Neither do we know if the main character is a he or she. In my interpretation of the short story, I have interpreted the main character as being a she. The main character is portrayed by a third person limited narrator, because we hear the story from the main characters point of view. Seen from the main characters point of view we get a description of the surroundings and feelings the main person is dealing with. The short story has two big flashbacks. Grace is first presented as the girl the main character falls in love with, with no risk of being hurt. On the way to the rental place the narrator looks back and remembers all the times it has been done before and in the end we see the narrator in Grace’s arms again. In the beginning of the short story, we get introduced to the “heart rental place”. This is a place where u can rent a heart...

...a person who is dating a lot of people and gets heartbroken every time they part ways so the main character goes to the heart rental place and rents a new heart to mend their broken heart. Throughout the story we hear about seven different partners, both men and women. The main character is currently dating Grace but looks back to past relationships. We are not told if the main character is male or female, so my interpretation is they could be gender neutral or a woman just like the author, it might be written from personal experience. She dates a lot of people, so she’s desperate for other people’s affection, but she can’t deal with the pain that comes with it, so every time she breaks up with someone she rents a new heart. She’s bisexual because she has partners that are both male and female. We don’t get any information about the setting, but it’s in the future because you can open your chest and switch out your heart for a new one. It’s a first-person narrative so we only see it from the main character's point of view. The rental hearts are a symbol of broken machinery that needs to be replaced, so the broken heart is equivalent to being heartbroken in real life. And opening your chest can be a symbol of opening your heart to other people. The whole story is a symbol of having your heart broken, wishing to replace your heart and to forget bad memories. Her first love was Jacob, and she was very in love with him. ‘Jacob was as solid and golden as a tilled field, and...

...feelings. To ask, “What is love?” would be the same as asking, “What is running?” or “What is swimming?” If you ever seen someone run or swim, you know exactly what running and swimming entail. The story “The Rental Heart” deal with love and the feeling you get when love fails you. When you are in love everything seems much better but when you break up everything turns dark and empty. It is for most people a fact, that you during your lifetime are going to get your heart broken. The heartbroken feeling of an endless pain that never goes away. Have you ever thought about, ripping out your broken heart, and change it with a new functional heart that will spare you from the heartbroken pain. No? Maybe it is because it is not a possibility in our world, but in “The Rental Heart” the reality is a bit different. The short story is a science fiction story written by the author Kirsty Logan in 2010. The story is told by a first person narrator who also is the protagonist of the story. Try to imagine a life where broken hearts is not an option. That is how the society works in “The Rental Heart”. It is a world where instead of feeling the awful pain of heartbreaks, you can just change your heart at the local heart rental place. Kirsty Logan uses the saying heartbroken literally in this short story. When we use the saying, we use it as a symbol of being sad and depressed over someone we love, which sometimes might feel like our heart has been shattered, even though that is not case. The...

...and having fun. Her image is falsely innocent, bubbly, and a little bit conformist. It does have a positive aspect on youth culture because she’s not over-sexualized like nine out of ten female artists, however is more tasteful when it comes to showing skin, and more subliminal when it comes to singing about sex. This is positive because a lot of teenage girls who look up to her notice that you don’t have to be promiscuous to be “hot”. I can relate to Katy Perry’s image sometimes because she tries to be different without going overboard, and I can relate to her lyrics because everyone has days that aren’t too great, even if it doesn’t have to do with a broken heart. I think that her message reaches out to youth culture in general, because teenage years can be hard sometimes. A lot of times girls, even boys with broken hearts can strongly relate to Katy Perry’s lyrics. Aside from her heartbroken songs, she sings about having fun such as “Last Friday Night”. This is a good reflection of youth because teenagers don’t have many concerns so they find it easy to party and have fun. Although the lyrics are a bit over-exaggerated, no one is to say that it never happens. Katy Perry also sings the song “Firework” which tends to spark a lot of confidence in teenagers, because now a days everyone is judgmental, and you always find flaws within you. With “Firework” it’s a little pick me upper, when you’re feeling down. Katy can easily be compared to Cindy Lauper. Firework-Katy...

...I have had a few heartaches throughout my life: my parent’s divorce, moms breast cancer, grandpas death, and having a bad break up. Everyone in their life goes through at least one heartache, or what some people may call a “heart break” or “heartbroken.” Life always throws things at you that you need to learn to deal with, through my experiences I have learned a few tricks to get through the bad times and come out as a stronger person. The first step you have to do is give yourself time to be sad. Give yourself at least two days where you can cry all you want, eat chocolate, lay in bed, let all those emotions pour out. After those two days, the number one thing to make your self feel better is to look your best. Its proven that if you make yourself look good, you start to feel good, it also brings back some of your confidence. The second step, make sure you surround yourself with people that make you happy and are able to talk to. Talking about how you feel to people you trust keeps yourself from keeping your emotions inside, because if that happens then your thoughts and emotions boil up inside until your going to have an emotional break down. No matter what happens and how low you feel, never push your friends or family away because those are the people that are always there for you and truly want the best for you. Try and keep your mind of things; hang out with friends, take up a hobby, focus on school. Opening yourself up to new experiences opens you up to new people...

...psychological description of the heart? What does it mean when you get your heart broken for the first time? Will it never heal? Can you ever fix a broken heart? In the short story the rental heart written by Kirsty Logan, we are introduced to the problem of a broken heart, and hos the protagonist in the story deals with having his/her heart broken repeatedly throughout the story. The short story is about a guy/girl telling us about his life with heartbreak, every relationship were he/she got his/her heart broke by the person he/she was in love with. It is about how he/she deals with the pain and sadness that comes with a broken heart. Every time a relationship ends the protagonist takes the broken heart out of his/her chest, and rents a new heart he/she can replace it with. The story is not written chronologically, it is set up like a time line, we start out in present time, and afterwards we go back in time as the protagonist talks about his/her former love stories. The first person the protagonist tells us about is Grace, and she is the last person we hear about. In this story, the view on the heart is different from how we look at the heart in real life, instead of the heart being a body part, it is viewed as a machine part, that you can easily take out and replace whenever it breaks. In the story both life and the body is compared to a machine, the machine cannot work if one of the parts is broken, as the body cannot work properly...

...Analysis of ”The Rental Heart” The Rental Heart is a story about heartbreak and having to cope with it afterwards. In this story however, it is possible to return the shattered heart and replace it with a new one. In a sense, you avoid the heartbreak and move on without the emotional scarring you endure from getting your heart broken. The story is set in a utopian world where it is possible to rent a mechanical heart thus not having to deal with any real emotions, particularly heartbreak. Starting with a four-year-old relationship ending and a corporeal heart shattered, we follow the love life of the narrator over many years until he/she finally, several rental hearts later, finds someone to love wholeheartedly again. The heart in this story is described as a mechanical one: a box where all emotions and memories of a relationship are stored until you replace it with a new one. Words such as, “sleeker”, “smaller” and “smooth” are used to describe the hearts. In the world we live in today, words such as those are usually used to describe a smartphone or a fancy car. The heart is therefore materialistic, something that can be bought and, when you are done using it, thrown away like garbage. The interesting part is that in real life, the heart does not possess any emotions or control how we feel about another human being. It is all in our heads: memories, feelings, pictures etc. are all stored in our brain. The heart is just a muscle that pumps blood around in our body to keep...
